资源摘要信息:"***是一个提供专业的DNS和IP查找服务的在线工具。它能够将域名或主机名转换为对应的IP地址,并对URL进行深度DNS查找,以展示各种DNS记录类型的信息。DNS查找工具的使用对网络管理员和IT专业人士来说非常重要,因为它有助于诊断网络问题、验证域名配置或进行安全检查。常见的DNS记录类型包括A记录、MX记录、NS记录、SOA记录和TXT记录。 A记录是最基本的DNS记录类型之一,它将一个域名映射到一个IP地址。MX记录用于指定邮件服务器的地址,NS记录指明了负责特定域名区域的DNS服务器。SOA记录包含了关于DNS区域文件的管理信息,如区域的主域名服务器、管理员的电子邮件地址以及关于区域文件的更新时间等。TXT记录是一种可以存储文本信息的记录类型,常用于SPF(反垃圾邮件协议)或其他需要通过DNS验证身份的应用。 除了提供这些记录类型的信息,***还能够为用户提供域名的反向DNS查找功能,即将IP地址转换回对应的域名。这对于追踪邮件来源、诊断网络问题以及确保网络安全至关重要。此外,该工具可能还支持PTR记录的查找,PTR记录是A记录的反向版本,它在反向DNS查找中使用。 在线DNS查找工具通常是基于Web界面设计,用户无需安装任何软件或进行复杂配置即可使用。它们通过发送DNS查询请求到DNS服务器,并展示返回的结果。在***这样的平台上,用户可以输入想要查询的域名或IP地址,并迅速获得相关DNS信息。此功能对于网络开发人员、系统管理员及任何需要验证域名设置的人员而言都极具价值。 由于DNS查找工具涉及敏感信息,它们通常会采用加密连接来保护用户的查询和结果数据。此外,为了提高效率和准确度,专业DNS查找工具可能会提供API接口,允许用户在自己的系统或应用程序中集成DNS查找功能。 ***的使用方法简单直观,即使是技术新手也能轻松地获取所需的DNS信息。这类工具对教育工作者和学生同样有用,因为他们可以用来学习和了解DNS的工作原理,以及它是如何支撑互联网运行的。随着互联网技术的不断发展,DNS查找工具也在不断更新,以适应新的网络环境和技术标准。"

请翻译:202.192.1.5 is making SMTP connections which indicate that it is misconfigured. Some elements of your existing configuration create message characteristics identical to previously identified spam messages. Please align the mail erver's HELO/EHLO 'icoremail.net' with proper DNS (forward and reverse) values for a mail server. Here is an example: Correct HELO/DNS/rDNS alignment for domain example.com: - Mail server HELO: mail.example.com - Mail server IP: 192.0.2.12 - Forward DNS: mail.example.com -> 192.0.2.12 - Reverse DNS: 192.0.2.12 -> mail.example.com Correcting an invalid HELO or a HELO/forward DNS lookup mismatch will stop the IP from being listed again. Points to consider: * Alignment: it is strongly recommended that the forward DNS lookup (domain name to IP address) and rDNS (IP to domain) of your IP should match the HELO value set in your server, if possible * The IP and the HELO value should both have forward and rDNS, and should resolve in public DNS * Ensure that the domain used in HELO actually exists! Additional points: * According to RFC, the HELO must be a fully qualified domain name (FQDN): "hostname.example.com" is an FQDN and "example.com" is not an FQDN. * The domain used should belong to your organisation. * HELO is commonly a server setting, not DNS. Contact your hosting provider for assistance if needed. You can test a server's HELO configuration by sending an email from it to helocheck@abuseat.org. A bounce that contains the required information will be returned immediately. It will look like an error, it is not. Please examine the contents of this email. If all settings are correct, you have a different problem, probably malware/spambot. Again, the HELO we are seeing is 'icoremail.net'. The last detection was at 2023-05-27 13:35:00 (UTC). For information on misconfigured or hacked SMTP servers and networks, please see this FAQ: https://www.spamhaus.org/faq/section/Hacked...%20Here's%20help#539 CSS listings expire a few days after last detection. You can always open a ticket (or update an existing one) to inform us when and how the situation was been secured.
